Question

A train, traveling at a constant speed of 22 m/s, comes to an incline with a constant slope. While going up the incline, the train slows down with a constant acceleration of magnitude 1.4 m/s2.
(a) Draw a graph of vx versus t where the x -axis points up the incline.
(b) What is the speed of the train after 8.0 s on the incline?
(c) How far has the train traveled up the incline after 8.0 s?
(d) Draw a motion diagram, showing the trains position at 2.0-s intervals.
